Definitions

  • the present invention relates to the field of dashboards for motor vehicles.
  • the present invention relates to the means lighting for such dashboards.
  • dashboards for motor vehicles comprising means complex lighting with multiple distributed lighting sources next to the dial associated with each hand and at least one guide optic interposed between said light sources and the needle as well as the dial, to ensure optimal lighting.
  • Document DE-A-19530420 describes an indicator element which can serve as a dashboard for a motor vehicle comprising a source luminous, a pointer indicator and a dial with areas reference value indicators arranged between the source and the indicator needle, as well as a movable colored band interposed between said dial and said source.
  • dashboards known are not entirely satisfactory, in particular due to their complexity, and their resulting cost.
  • the present invention now aims to improve the dashboards for motor vehicles.
  • a part of the dashboard of motor vehicle comprising a box 10 provided at its rear part with a printed circuit 20 and its front part of a dial 30 associated with a needle indicator 50.
  • the housing 10 can be the subject of numerous embodiments. II is preferably formed by opaque plastic molding.
  • the box 10 can be made of white plastic.
  • This housing can be coated internally with a reflective varnish.
  • the printed circuit 20 carries a light source 40, as indicated previously.
  • This light source 40 is preferably formed by a lamp filament filament type CMS (Component suitable for Assembly surface).
  • It can preferably be a 1.2 W source powered under 12 V.
  • the source 40 is preferably centered on an axis orthogonal to a plane containing the printed circuit 20.
  • the light source 40 can be centered on an axis parallel to the printed circuit 20 or inclined with respect to this one.
  • the printed circuit 20 can of course carry other components, such as power control and indicator management circuits, or even control devices such as logometers, motors step by step or all equivalent means.
  • the dial 30 extends parallel to said printed circuit 20. It is preferably made of a polycarbonate plastic sheet at less partially transparent or translucent, such as the material marketed under the name "Makrofol" (Trademark), with ranges screen printed corresponding to the reference values associated with the needle 50 and / or associated acronyms or symbols.
  • a polycarbonate plastic sheet at less partially transparent or translucent, such as the material marketed under the name "Makrofol" (Trademark), with ranges screen printed corresponding to the reference values associated with the needle 50 and / or associated acronyms or symbols.
  • the needle 50 has an index 51 formed from an optically material transparent, forming an optical bar, linked to a hub 52 extended by a tip 54 by which the needle 50 is fixed, preferably driven on the axis of a rotary motor means.
  • the end piece 54 can be opaque.
  • This rotary motor means is not illustrated in the figures for simplify the illustration. It is preferably a logometer or a motor step by step, or by any equivalent means.
  • the hub 52 is advantageously covered, at least partially, on the front, by an optically opaque cap 53.
  • the element for fixing the needle 50, provided on the hub 52, passes through a passage 31 formed in the dial 30.
  • the printed circuit 20, the dial 30 and the housing 10 define in combination of a chamber 12 in which the light source is placed 40.
  • the light source 40 illuminates directly, without a guide interleaved optics, both the needle 50 and all of the indicator areas associated reference values provided on the dial 30. It should be noted that no obstacle should disturb the light source 40 illuminating the needle 50 and the dial 30.
  • the light source 40 is placed in a plane of symmetry of the indicator areas provided on dial 30. This plane of symmetry coincides with the section plane of the appended figure.
  • the light source 40 is centered on a generator G resting on an edge of the passage 31 and inclined relative to the axis of rotation of the needle 50 by an angle A of between 10 ° and 40 °, advantageously between 20 ° and 30 °, very preferably of the order of 25 °.
  • the light source 40 is placed on the printed circuit 20 at a distance from the axis of rotation of the needle 50 equal to twice the diameter of the passage 31.
  • the length of the chamber 12, considered parallel to the circuit printed 20 and on dial 30, is between 5 and 25 times, advantageously 10 and 20 times, very preferably around 15 times the diameter of the passage 31.
  • the height of the chamber 12 is itself advantageously of the order of twice this diameter.
  • the diameter of the passage 31 is considered to be substantially equal to the diameter of the area of the needle 50 capable of receiving the light flux coming from the light source 40.
  • the housing 10 defines a opaque ring 14 which surrounds the passage 31 on the rear surface of the dial 30.
  • dashboard In the context of the invention, the expression “dashboard” must be understood in a broad sense, such a dashboard can for example have one or more needle indicators.
  • a weft and / or equivalent means such as varnish coating or the like may be provided on the rear surface thereof.
